Imidazole and triazole head group containing polydiacetylenes for colorimetric monitoring of pH and detecting HCl gas

Abstract

The family of conjugated polymers known as polydiacetylenes (PDAs) have been extensively utilized in designing stimuli-responsive colorimetric and fluorometric sensors. In the current study, we developed highly sensitive and rapidly responsive colorimetric chemosensors comprised of PDAs bearing imidazole (PDA-Im) and triazole (PDA-Ta) head groups, for the determination of pH and the detection of HCl gas. In solution, PDA-Im and PDA-Ta display distinct colorimetric changes from blue-to-red according in response to pH changes. Also, a PDA-Im film was fabricated to detect HCl by a visibly observed blue-to-red color change.
